Phenylalanine ammonia-lyase (PAL, EC 4.3.1.5) and cinnamic acid 4-hydroxylase (CA4H, EC 1.14.13.11) undergo concomitant increases in activity after a 2 h lag following disc preparation and illumination. The increases in PAL and CA4H activity can be inhibited by actinomycin-D, cordycepin and cyclohex
## Catalytic activities of o-chymotrypsin and subtilisin Car&berg for transesterification of N-acetyl-L-tyrosine methyl ester in ethanol markedly increased by decreasing the amount of the enzymes in the reaction mixtures. The results were kinetically attributed to changes in KM and k,,, due to for
